Part Details:

74VHC595 8-Bit Shift Register with Output Latc May 2007 74VHC595 tm 8-Bit Shift Register with Output Latches Features General Description High Speed: t = = PD 5.4ns (Typ.) at VCC 5V The VHC595 is an advanced high-speed CMOS Shift Low power dissipation: I = = Register fabricated with silicon gate CMOS technology. CC 4µA (Max.) at TA 25°C High noise immunity: V = = It achieves the high-speed operation similar to equiva- NIH VNIL 28% VCC (Min.) lent Bipolar Schottky TTL while maintaining the CMOS Power down protection is provided on all inputs low power dissipation. Low noise: V = OLP 0.9V (Typ.) This device contains an 8-bit serial-in, parallel-out shift Pin and function compatible with 74HC595 register that feeds an 8-bit D-type storage register. Thestorage register has eight 3-STATE outputs. Separateclocks are provided for both the shift register and thestorage register. The shift register has a direct-overridingclear, serial input, and serial output (standard) pins forcascading. Both the shift register and storage registeruse positive-edge triggered clocks. If both clocks are hes connected together, the shift register state will always beone clock pulse ahead of the storage register. An input protection circuit insures that 0V to 7V can beapplied to the input pins without regard to the supplyvoltage. This device can be used to interface 5V to 3Vsystems and two supply systems such as batterybackup. This circuit prevents device destruction due tomismatched supply and input voltages.
